2025 ROG Strix Scar 18 vs 2024 Model
| Feature | Scar 18 (2024) | Scar 18 (2025) |
|---|---|---|
| GPU | RTX 4080 | RTX 5090 |
| Display | 240Hz IPS | 240Hz Mini-LED HDR |
| Cooling | Dual-fan | Tri-Fan + Vapor Chamber |
| Performance Gain | — | +15–25% CPU, +10–20% GPU |
One of the most notable 2025 upgrades is the complete overhaul of the core silicon architecture. The Intel Core Ultra 9 275HX chip offers a significant performance boost, delivering 15–25% gains in multi-threaded workloads over the previous generation’s Core i9-14900HX/13980HX processors.
But the GPU update is equally notable. The latest Strix Scar lineup utilizes the NVIDIA GeForce RTX 5090 mobile graphics card with massive 24GB of dedicated VRAM.
Compared to Other 2025 Flagship 18-inch Gaming Laptops
To fully appreciate the Asus ROG Strix Scar 18 (2025), a direct comparison with its two main 18-inch rivals—the MSI Raider 18 HX AI and the Razer Blade 18—is necessary.
MSI Raider 18 HX AI (Max Performance)
The MSI Raider 18 pushes for maximum performance. It features the Intel Core Ultra 9 285HX processor, which is architecturally a step above the 275HX, paired with faster DDR5-6400MT/s RAM. The Raider boasts a higher 260W combined system power limit facilitated by MSI OverBoost Ultra Technology, which theoretically positions it as the benchmark leader. However, this power and cooling capacity result in a heavier machine, weighing almost eight pounds. The display options often include a demanding 4K 220Hz panel, which requires substantial GPU power to drive.
In contrast, the Asus ROG Strix Scar 18 2.5K Mini-LED ROG Nebula HDR panel provides exceptional brightness, color depth, and contrast, while ensuring the RTX 5090 can consistently drive the native resolution at high frame rates, maximizing the potential of the 240Hz refresh rate.
Razer Blade 18 (Performance + Portability)
The Razer Blade 18 shares the same Intel Core Ultra 9 275HX and access to the RTX 5090 GPU as the Scar 18. Its core differentiator is its focus on chassis refinement and portability, resulting in a weight of only 7.06 pounds. But it comes with one important trade-off: Razer imposes a hard maximum GPU TGP of 175W for the RTX 5090. This limitation means that while the laptop is highly capable, its sustained peak graphical performance will trail behind the Strix Scar 18 and Raider 18, which operate at higher dynamic power levels.
Resale Value: Why Asus Gaming Laptops Hold Their Worth
Asus ROG laptops consistently rank among the most desirable secondhand gaming machines, and the latest 202Scar 18 is no exception. Thanks to its premium build quality, cutting-edge specs, and strong brand reputation, it retains resale value better than many competitors. The inclusion of top-tier components, such as the RTX 5090 and mini-LED display, ensures relevance for years to come, while the aluminum chassis and customizable RGB lighting appeal to buyers seeking both performance and aesthetics.
But notebook depreciation rates are high, and, unfortunately, Asus ROG is not immune to them. Therefore, if you plan to resell your pre-owned gaming computers, it is advisable to do so as soon as possible, ideally within the first three to five years of use.

Verdict: Power With a Price
